你能帮我解决这个SUDS/SOAP问题吗？

Question

所以我试图使用SUDS 访问这个api https://www.clarityaccounting.com/api-docs/.这是应该工作的代码:

from suds.client import Client
client = Client('https://www.clarityaccounting.com/api/v1?wsdl')
token = client.service.doLogin('demo', 'demo', 'www.kashoo.com', 'en_US', 300000)

但我得到这个错误:

WebFault: Server raised fault: 'No such operation:  (HTTP GET PATH_INFO: /api/v1)'

他们的支持人员说请求应该如下所示:

<SOAP-ENV:Envelope
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:api="http://api.service.books/">
  <SOAP-ENV:Body>
     <api:doLogin>
        <username>demo</username>
        <password>demo</password>
        <siteName>www.kashoo.com</siteName>
        <locale>en_US</locale>
        <duration>300000</duration>
     </api:doLogin>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

但是SUDS'看起来像这样:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope 
xmlns:ns0="http://api.service.books/" 
xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Header/>
   <ns1:Body>
      <ns0:doLogin>
         <username>demo</username>
         <password>demo</password>
         <siteName>www.kashoo.com</siteName>
         <locale>en_US</locale>
         <duration>300000</duration>
      </ns0:doLogin>
   </ns1:Body>
</SOAP-ENV:Envelope>

我是一个真正的SOAP和SUDS新手,但我听说SUDS是从这里使用的最好的SOAP库:Python存在哪些SOAP客户端库,它们的文档在哪里？

所以我的问题是什么是不同的关键部分,使请求失败,如何配置SUDS发送格式正确的请求？

乍一看,您遇到的问题就是使用SSL.您正在访问https URL,默认情况下,suds.client的传输处理程序会与http进行对话.

问题
如果您查看WSDL的底部,它将默认位置指定为http://www.clarityaccounting.com/api/v1http URL,但WSDL是SSL.

 <wsdl:service name="v1">
    <wsdl:port binding="tns:v1SoapBinding" name="BooksApiV1Port">
      <soap:address location="http://www.clarityaccounting.com/api/v1"/>
    </wsdl:port>
 </wsdl:service>

如果您对该URL执行http GET,则会收到您收到的错误消息:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <soap:Body>
        <soap:Fault>
            <faultcode>soap:Server</faultcode>
            <faultstring>No such operation:  (HTTP GET PATH_INFO: /api/v1)</faultstring>
        </soap:Fault>
    </soap:Body>
</soap:Envelope>

解决方案
要解决此问题,您需要在调用Client构造函数时覆盖默认位置以使其与https保持一致:

>>> url
'https://www.clarityaccounting.com/api/v1?wsdl'
>>> client = Client(url, location='https://www.clarityaccounting.com/api/v1')
>>> token = client.service.doLogin('demo', 'demo', 'www.kashoo.com', 'en_US', 300000)
>>> token
(authToken){
   authenticationCode = "ObaicdMJZY6UM8xZ2wzGjicT0jQ="
   expiryDate = 2010-03-05 12:31:41.000698
   locale = "en_US"
   myUserId = 4163
   site = "www.kashoo.com"
 }

胜利!

用于将来调试目的的专业提示:打开完整的日志记录调试.SUDS使用标准logging库,因此它为您提供了很多控制.所以我把它全部归结为DEBUG:

import logging
logging.basicConfig(level=logging.INFO)
logging.getLogger('suds.client').setLevel(logging.DEBUG)
logging.getLogger('suds.transport').setLevel(logging.DEBUG)
logging.getLogger('suds.xsd.schema').setLevel(logging.DEBUG)
logging.getLogger('suds.wsdl').setLevel(logging.DEBUG)

这是帮助我缩小范围的原因,因为它显然是在发送http:

DEBUG:suds.transport.http:sending:
URL:http://www.clarityaccounting.com/api/v1
(xml output omitted)

然后响应说:

DEBUG:suds.client:http failed:
